This appears to be a pseudonym for Irwin Abrams. It is rather perplexing I could find no information at all about this fantastic band. That Irwin Abrams was a violinist and bandleader in the 1920's is the only fact I could retrieve... anyone knows more? From period paper excerpts I could find out the Manger Hotel in New York seems to have been the live performing location of Irwin Abrams' band. The vocal is credited to Les Rockwell, apparently a pseudonym for Les Reis.
